Lag spiking issues mid song

[MelEtoile]

Hello! Not sure if I should've included this under another discussion or not but! I recently just bought this game and am absolutely loving it :). I have been playing Project Diva games for years so It's very exciting to see this game on pc now!
I did however start to experience lagging issues mid song while playing various charts. I would be playing a song and all of the sudden the entire game would freeze for 1-2 seconds and desync the notes just a little bit, enough for me to lose my combo, and then would go back to normal.
It had started happening on almost every song and I only have four hours on this game. At first I thought it might've been the PV that was playing in the background causing the lag but I've found that the lagging issues only happen in arcade mode as I spent a lot of time earlier this week just watching the PVs for hours and experienced no lagging issues there. Because I was experiencing this issue I decided to go and look to see if any other people were having the same issue as me and turns out there are a ton! I've tried lowering my graphics settings to see if it would fix the issue and of course like others have stated it does not. My pc is more than capable of running this game so I was very frustrated to run into this issue. I've heard people talking about how Denuvo is in this game and how that is most likely the cause for all these issues. I'm posting this to see if there's even more people experiencing these lagging issues within the game and hopefully Sega will see all of these complaints and fix these issues within the near future. I'm not too worried about it as Megamix+ is still fairly new but I very much hope they will fix these issues cause they are very very annoying!! :C It sucks to have spent money on this game and run into these problems. Also I was wondering if anyone maybe had some more troubleshooting or lag fixes they could share to prevent or stop this issue. Thank you !

I have the same problem playing with Steamdeck and also with a new PC (I7 12700 GeForce RTX 3060 12GB 32GB RAM DDR5).

I get these too, as well as many others. Some people say it's Denuvo; I have evidence that it's caused by background downloads that happen while you're playing. Either way, the only surefire (mostly I guess) way I know of to avoid them is to play with your internet disabled.

Supposedly Sega doesn't update their PC games after two months, so if you're hoping it'll be fixed, I wouldn't count on it. As you said, there have been many people complaining about this since launch, but Sega doesn't seem to have improved it even after two updates.

I can add that I wound up breaking my Windows Update for several months without realizing it while trying to help the game and during those months the only intrusive stutter I had was while installing a different game. Once I fixed it, my game had several stutters next time I played. Can't guarantee results, but you can try disabling the wuauserv Service in Task Manager's Services tab before playing and see if it helps.

You can also hope some of the mods out there, the frame rate enhancer etc. might help you, but they don't seem to help me.

Running the game from a different disk drive than Steam / most of your games are installed to has helped some users.

The Steam client updates application manifests in the background as updates are published, so the more games you have installed to the same disk drive as Hatsune Miku, the more likely there will be a conflict for read/write during these updates.
